ATTACHMENT FOR POLES FOR ELECTRIC WIRES.

SPECIFICATION forming part of Letterslatent No. 456,683, dated July 28,1891.

Application filed July '7, 1890.

To all whom it may concern.-

Be it known that I, EDMOND VERSTRAETE, of the city of St. Louis, in theState of Missouri, have invented a certain new and useful Improvement inAttachments for Poles for Electric \Vires, &c., of which the followingis a full, clear, and exact description, reference being had to theaccompanying drawings, forming part of this specification.

My invention relates to an improved cap for poles for electric wires;and my invention consists in features of novelty hereinafter fullydescribed, and pointed out in the claims.

Figure I is a side elevation illustrative of my lnvention. Fig. II is asimilar view showing another side to that illustrated in Fig. I. Fig.III is a vertical section taken on line III III,Fig. II. Fig. IV isavertical section showing a different method of insulating the cap fromthe pole to that shown in Fig. III, and Fig. V is a horizontal sectiontaken on line V V, Fig. I. Referring to the drawings, 1 represents theupper end of a pole for electric wiressuch, for lnstance, as thesupporting and guard wires to an electric road and the wires of anelectric light.

2 represents a cap or hood fitted over the upper end of the pole andinsulated therefrom by rings 3, as shown in Fig. III, or by means of acontinuous insulating-cap l, as shown in Fig. IV. The upper one of therings 3, it will be seen, has an annular flange 3, which rests on thetop of the pole, thus forming aninsulatlug-cap. It is of course evidentthat if a wood pole orothernon-conductor of electricity is used aninsulator 4t willnot be required, and the cap may be simply fitted onthe end of the pole.

5 represents arms or projections on the cap which support knobs 6, towhich the wires of an electric lightmay be seen red, the knobs beingformed on the ends of stems 7, fitting in sockets in the arms orprojections 5. (This is clearly shown in Fig. III.) The cap is furtherprovided with lateral ears 8 9 for the at tachment of the supporting andguard wires of an electric road. The supportingwvires would be connectedto the ears 8 and the guard-wires to the ears 9. There are two ears 8and two cars 9, as shown in Fig. V, each pair of cars being separated bya space 10 Serial No. 357,944- (No model.)

and provided at top with a strengthening-web and water-shed S.

11 represents bolts provided with a noncircular head 12 and which passthrough the ears 8 9. There is a bolt for each pair of ears. Thesupporting and guard wires are made fast to the cap through means ofthese bolts, as shown in Fig. V, the wires being made fast to andwrapped around the bolts. For the purpose of regulating the tension ofthe wires the bolts can be turned in the cars by applying a suitablewrench to their heads 12, and they are held to any adjustment by meansof pins 13, which pass through perforations ll in flanges or collars 15on the bolts, preferably 011 the ends of the bolts having the heads 12,and which also pass through perforations in the ears, as shown in Fig.V. It will thus be seen that each pair of cars is provided with aWindlass, andthat by removing the pins 133 and turning the bolts 11 thesupporting and guard wires may be tightened or loosened, and that byreapplying the pins the bolts will be held to their adjustment.

By the use of my invention the wires of an electric light can besupported on the same cap to which the supporting and guard wires of anelectric road are secured, and the supporting and guard wires can bevery quickly and easily adjusted in tension.

I claim as my invention 1. The combination, with the pole, of aninsulating-cap fitted on the end of said pole, an insulating-ringfittedon said pole at a distance below said insulating cap, and the metalliccap 2, having wire-supporting knobs fitted over said insulating cap andring, substantially as set forth.

2. As an article of manufacture, a cap adapted to fit over the end ofthe pole,having lateral arms 5, provided with sockets at their outerends for the reception of wire-supportin knobs, and two pairs of carsarranged one below the other, each pair having a strengthening-web andwater-shed 8 and being provided with a windlass, said cap, arms, andears being formed integral, substantially as set forth.

EDMOND VERSTRAETE.
